All this speculation is based on this article: http://stlplaces.com/night_vision_red_myth/
Great article, found it searching here.
OK, here is the idea.
One light body and one power supply, with three controls be they button, dial, whatever.
There's a dark red spot beam, a blue/green (teal?) flood beam, ideally with the center blocked or faded, and there is a white beam maybe it should be spot or maybe a mix of spot and flood.
All have very low lows.
Since it's a low powered light it could be small and ergonomic, maybe set up as an armband, ring, or clipped for a hat bill.
